[x-posted at the Sapphire forums]
Let me preface this post by stating that I have read a ton of threads on the 1950PRO issues, and the genereal troubleshooting threads here. What I am looking for are answers specific to my build. I built the computer in my sig January of this year, first attempt at building a PC. As you can see I was working on a budget. I initially was going with a 7900GS video card, but swapped it for the 1950PRO at the last minute due to stock issues, but was pleased to find that the 1950 was more cost effective anyhow. Put it all together within a couple hours with no problems whatsoever, and have had no problems with it until last weekend. I mainly use the PC to play WoW, but last weekend my brother dropped off Oblivion and FEAR. The 1950 handles both games like a champ, running at maxed/nearly maxed settings 1440x900 at good frame rates. That said, after playing Oblivion for a good six hours my PC just restarted. It happened a 2nd time the next day after about an hour of play. Also when playing Fable it has locked up (forcing hard reboot) twice during zone changes, and finally restarted on my once while playing WoW (right after the Fable issues).
I am 99% sure this is a power / heat issue, the latter being a syptom of the prior. I was unaware of the neediness of the card when I swapped it for the 7900GS, but understand now that my PSU cannot supply the 1950 properly.

When I first built the PC, the video card idled at round 48 Celsius, but now idles around 52. This is most likely due to the fact it is no longer below 30 outside and my apartment is no longer an icebox. I know the 1950Pro runs hot, I see it get up to 75 Celsius regularly (probably over). I am pretty sure the higher temperatures are straining my already inadequate PSU, causing the reboots/lock ups. Or are the high temps are being caused by the inadequte PSU. (I'm not the most hardware-savvy person, so *shrug*.) I do not think my card is merely 'overheating'.
All that said, I see a few options (with cost):
1. RMA the card for one that is less power hungry. ($50-75) Don't really want to do this, as it seems like a cop out and the card does perform well other than the problems listed above. There are no artifacting or weird graphics issues at all.
2. Purchase a new power supply. ($115-150) I understand that this is the best answer, but its also the most expensive. I probably wouldn't be able to do this for a month or so.
3. Purchase the Thermaltake 250W GPU Power Supply. ($50-75) From what I can tell this should solve my problem. But I am not sure.
So my questions are:
A. Based on my build, would the Thermaltake GPU Supply be sufficent for my card? If so, is there anything else I need to worry about using that PSU?
B. If not, what is the most cost effective power supply that will work? (Both single rail and dual rail, but if I am going to purchase a new PSU I'll probably go with single.)
C. Most importantly, by running my PC as is until I choose/implement a solution am I putting any of my hardware at risk? Worst case, it will take me a month before any change is made. I do have another video card (6800XT) I could swap in, in the mean time, that would probably be fine with my current PSU.
(Other details: I am currently running the newest Catalyst driver and am using CCC to measure the card temps.)
